Production of gynogenetic and polyploid catfish by pressure-induced chromosome set manipulation

Abstract:

Channel catfish (Ictalurus punctatus) eggs fertilized with sperm from blue catfish (I. furcatus) or channel catfish (60 or 90 s UV-irradiated, 0.08 or 0.12 J/cm2, respectively; 20-30% motility) were subjected to early hydrostatic pressure (5 min post-fertilization; 8000 psi; 3 min duration) to produce meiotic gynogens or late hydrostatic pressure (90 min post-fertilization) to produce mitotic gynogens. Polyploid hybrid catfish (I. punctatus X I. furcatus) were produced using eggs fertilized w...
